Confined aquifer fluid-solid coupling analog simulation experiment device

Abstract

The invention discloses a confined aquifer fluid-solid coupling analog simulation experiment device. The device comprises a base, a left vertical frame, a right vertical frame, a cross beam and splittype side protection plates, the left vertical frame and the right vertical frame are installed on the left side and the right side of the base respectively, the two ends of the cross beam are installed at the upper end of the left vertical frame and the upper end of the right vertical frame respectively, the two ends of the split type side protection plates are detachably connected with the leftvertical frame and the right vertical frame respectively, and the front split type side protection plate, the rear split type side protection plate, the left vertical frame, the right vertical frame and the base define an analog simulation space. The device can be used for similar simulation test research of confined aquifers in mining and is high in matching degree with the actual situation.

Description

technical field [0001] The invention relates to the technical field of similar simulation of coal mine mining. Specifically, it is a similar simulation experiment device for fluid-solid coupling in confined aquifers. Background technique [0002] Coal mine water damage is one of the main safety hazards in the process of mine construction and production alongside gas and roof accidents. In recent years, the problem of coal mine water disasters has become more and more serious in our country. Among the serious accidents in coal mining areas, the number of deaths caused by coal mine water accidents is particularly large, and the number is second only to the death toll caused by gas accidents. In terms of frequency, it ranks third only after coal mine gas and roof accidents. According to relevant research reports, after the 1980s at the end of the last century, over the past 20 years, more than 250 mines in my country were flooded, more than 1,700 people died, and economic los...

Problems solved by technology

[0004] At present, in the prior art, there are simulation experiments on the aquifer in the shallow overburden layer. For example, in the construction of municipal engineering, the aquifer in the shallow overburden layer is usually sealed with a glass plate, and when the shallow overburden layer is disturbed The movement of the aquifer changes regularly, but when the shallow overlying soil layer moves, the water in the aquifer will flow out from the gap between the glass plate and the soil layer, which cannot realize the true sealing of the aquifer, let alone simulate the pressurized water in mining There are also similar simulation test studies on the layer; there are also foam glue or sealants used to seal between the glass plate and the aquifer, but the foam glue or sealant is bonded to the glass plate, and the shallow overlying soil layer is greatly disturbed or collapsed. When the aquifer is separated from the foam glue or sealant, the sealing effect of the aquifer cannot be achieved

Therefore, there is no relevant experimental device for confined aquifers in the prior art
